Table 2.
Fractions of binary systems in our model grids that are predicted to form double helium stars for each initial mass-ratio.
| qi | 1.0 | 0.9 | 0.7 | 0.5 | Total |
|---|---|---|---|---|---|
| Standard Grid | 5.81×10−3 | 2.92×10−3 | 1.15×10−3 | 0 | 9.58×10−4 |
| Enhanced Grid | 8.73×10−3 | 7.61×10−3 | 4.14×10−3 | 0 | 2.28×10−3 |
Notes. A Salpeter primary mass distribution (dN/dM ∝ M−2.35), a flat distribution in log of initial orbital period and a flat initial mass-ratio distribution have been assumed. The total is given by the integral over mass-ratio.
